I had a year-old ACDelco HEI go out on me just a few weeks ago. A new coil and module from Advance Auto Parts did the trick. I've since upgraded to Davis Unified Ignition 50K coil and their module. Runs even better now! The USA-made module from Advance is now in the glovebox as a spare.

Frankly, I'd avoid distributors with no-name labels (Yicton?) or appear to be made in China. I've read that there is a large production run of HEI distributors that are known to be defective and are being resold online.
